The 46-year-old actor is worried his trademark locks are making him look too old and is planning to change to a more youthful color.

He said: "My hair's too gray, much too gray!"

"I will have to consider dyeing it. I've been thinking a lot about it lately. First I'm going to start dyeing my eyebrows, just to see how it works. And then I'll go to the hair. Start slowly."

The 'Leatherheads' star also says he has gone past the stage of having a mid-life crisis.

He said: "I going to be 47 in May. But there's no mid-life crisis for me yet. Although I'm 46 and I don't know a lot of 92-year-olds so maybe I'm past my mid-life. I've always tried to pick out the things that are good in life and enjoy them because there are tremendous amounts of ways to find the bad."
